Boot File System
SVR4, UnixWare[citation needed ] |
|---|
The Boot File System (named BFS on Linux, but BFS also refers to the Be File System) was used on UnixWare to store files necessary to its boot process.[1]
It does not support directories, and only allows contiguous allocation for files, to make it simpler to be used by the boot loader.
Implementations
Besides the UnixWare support, Martin Hinner wrote a bfs kernel module for Linux that supports it.[2]
He documented the file system layout as part of the process.[3]
The Linux kernel implementation of BFS was written by Tigran Aivazian and it became part of the standard kernel sources on 28 October 1999 (Linux version 2.3.25).[4]
The original BFS was written at AT&T Bell Laboratories for the
BFS was the first non-S5[clarification needed] (System V) Filesystem written using VFS (Virtual Filesystem) for AT&T UNIX.
